Isabel Allende

I was such a sullen, angry, sad kid. I'm sure there are writers who have had happy childhoods, but what are you going to write about? No ghosts, no fear. I'm very happy that I had an unhappy and uncomfortable childhood.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
